These men's Compression Tights from 2XU are engineered for muscle support: enhancing power, endurance and recovery. Targeted compression increases blood flow and oxygenation to the major muscle groups, allowing them to work harder and more efficiently. It also prevents lactate build up, creating a faster recovery time after exercise. By reducing the oscillation in muscles it reduces tears and damage, helping to prevent injuries.The tights are made with PWX FLEX fabric, a strong and stretchable material that springs back to its original shape ensuring it keeps its close, compressed fit after regular wear.
